- The pulleys E and 'F are connected with a suitable source of powerv by means of belts.

The source of motion in the-belts may either be of uniform speed and thevariation brought about by dilferent sizes of the pulleys E and F or the motion of the belts themselves may receive difierentspeed's. The lateral motion of the grooved collar I carries the double ended pawl H into engagement in the first quently transmits avfast speed to the shaft D and feeder 0. When the carton or other re= ceptacle has received nearly its complement of material, the weighing-beam commences to rise, and thus brings the point P into electrical-contact with :the small secondary weigh- This causes electrical co'nne'c to its magnet N, releasingthefork-lever J.

Thefo'rk by reason "of i ts springj throws "the i w pawl, H into vengage'me'n't with the ratchet on the slow-speed pulley F. This immediately ream the "S e h ha a nder.

sides the functions already described, performs the additional and desirable function of breaking the electric circuitimmediately the weighing operation=is completed by removing the weight entirely from the weighing-beam, thus permitting it to drop out of electric connection with the contact-points. The notched T-lever U forms alternately a lock for each member of I the duplex Weighing-platen.

In filling small or short cartons it may be desirable to reduce the length of the suspended stream or, inother words, reduce the distance between the end of the supply-spout and the carton or its support. This may be accomplished by either or both of the means shown in the drawings-that is to say,the telescopic spout may be moved down the desired amount or the weighing-platen, with its connections, may be raised on the rods R R. The ratchets r W, with the spring-pawls 1" r secure the device at the desired elevation.

The telescopic character of the connecting-7' rod 1) admits of ready adjustment to conform with the altered requirement, I v I It is evident that Inanychanges may be made in the mechanical devices andarrange- ,ments and'proportions'of the parts to adapt this invention tothe many forms of scales used in various branches of industry and many modifications will readily suggest themselves to mechanics skilled in the arts involved which may be advisable under various conditions without departing from the ,of parts herein shown; but
